WiMAX is short for Worldwide Interoperability for Microwave Access (International Interoperability for Microwave Access), represented in IEEE standard: 802.16, wireless networking regular that defines the metropolitan region. It can be a wireless technology (wireless), broadcast by radio, with incredibly excellent capabilities, which in the future will dominate the worldwide telecommunications industry.
Now, the possibilities of accessing the web by a user are restricted to 3 categories:
- Dial-up access (a modem that connects towards the Web through a telephone line with a small access speed)
- Access by way of WiFi (Wireless Fidelity “- the wireless connection from anywhere within an area in which there is certainly a WiFi router to get a limited distance)
- Access using Broadband (cable broadband connection, high speed, employing the telephone line or network cable)
Standard 802.16
IEEE or Institute in Electrical and Electronics Engineers is an international non-profit expert sort that defines the requirements, publish articles and lectures in the field of advancement in electronics and electrical technology. This organization has over 365,000 members in more than 150 countries. If a functioning electronic gear (implementation, testing, applications made use of) right after a typical IEEE 802.16 for instance, then it is approved as a device that supports WiMAX, as well as other equipment, can be interconnected using the same label.
WiMAX has been developed by the IEEE in several stages because of the early 80s and needs to culminate in 802.16m (WiMAX 2.0) soon. Initially wanted to perform with broadband technologies frequencies above 11 GHz, but the 2-11 GHz variety was introduced, to make use of diffraction, and function in environments with obstacles, not simply in space. Probably the most preferred sections are on the 802.16d common for fixed terminals, and 802.16e, for mobile terminals. Frequencies that might be utilized in customer gear, and are currently licensed in some nations are 2.5 GHz, 3.5 GHz, and 5 GHz.
WiMAX Options
Demand for wireless networks has grown explosively in current years, and as a result, started to develop information services to three-generation, 3G, and 3.5G These, having said that, still will not supply higher speeds comparable to these of terrestrial broadband networks. Enhancing the variety and keep away from the effects of multipath propagation, could be the 4th generation of networks, namely 4G: WiFi, WiMAX, LTE, which breaks the barriers of limitation in speed for extended distances and are designed according to IP because of the start out.
WiMAX against 3G enhancements:
- Is primarily based only on IP
- utilized the technique of orthogonal frequency division multiplex (OFDM and OFDM)
- makes use of time-division duplexing with (TDD)
- makes use of adaptive modulations
- approaches most effective error correction
- Projects for advanced antenna systems
Thus, via WiMAX transmissibility can give all services by way of the internet (IP) VoIP (Voice over IP), video telephony, video conferencing, navigation by way of HTTP (browsing), e-mail, file transfer (FTP) access to databases and others. Also, you may interconnect networks, such as WiFi.
Invariably, the future of telecommunications sounds straightforward like this: WiMAX. It’s going to replace most networks today known and applied by humans: the household (for internet access in your computer system, the cable television, and telephony), those in workplace buildings, schools along with other institutions.
